When I send a mail to a third party with bcc to myself, the third party receives the mail but the bcc does not arrive in my In Box. Until some weeks ago I could do this. I also no longer can send a mail from WLM back to myself via WLM. The mails leave the Out Box and show in the Sent Box with desired addresses.

My ISP is British Telecom who reports this is a fairly common problem and is associated with "the SMTP server" operation of WLM. They report "Microsoft can fix the problem" but WLM is no longer supported.

Any help appreciated.
